Australia have opened their World Cup bank account with a healthy deposit, a deposit England will still be trying to wipe off themselves after their opening match.

Aaron Finch's sweet century in front of his Melbourne homies was the highlight of the game although Glen "Smacks Well" Maxwell continued his run of of excellent form with a quick 66 (44 balls). It was also nice to see Capn Bailey pitch in with a sharp 55 helping the team to a near MCG one day record total of  342.

England's greasy palms didn't help the tourists any as they dropped Finch on the second ball he faced and continued to look like over cooked cabbage in the field for a good portion of the game. A few brilliant deliveries from Stuart Broad had Australia buckling at 3 for 70 but the pressure soon dissipated as the Australians got on with the job. Steve Finn who'd been belted around the park for most of the game somehow pulled off a demurely celebrated hat trick at the end of the game although it's probably not one he'll glowingly retell to his grandchildren.

Dropped on the second ball he faced, opening batsman Finch blasted 135 at his home ground to lay the platform for victory as the co-hosts piled on 9 for 342, two runs shy of the venue's one-day international record.

All-rounder Mitchell Marsh then took a career-best 5 for 33 as Australia put on a ruthless Valentine Day's display in the field that amplified the abysmal nature of its opponents' earlier efforts.

Having reprieved bulky opener Finch, England let a string of chances go begging, dropping catches and missing run-out opportunities to set a miserable tone for the start of its campaign.

It had reduced Australia to 3 for 70 but released the pressure and Australia's formidable batting line-up duly went into punishment mode.

After stand-in skipper George Bailey (55) teamed with Finch for a 146-run partnership, pugnacious all-rounder Glenn Maxwell smacked 66 off 40 balls.

Ironically, Steven Finn, who like his colleagues had been thrashed to all corners of the ground, became the first England bowler to take a World Cup hat-trick by dismissing Brad Haddin, Maxwell and Mitchell Johnson in the last three balls of Australia's innings.

He finished with a hugely expensive 5 for 71 and seemed embarrassed by his achievement.

It was to be a brief moment of celebration for the English, who were all but beaten by the 18th over of their chase, when captain Eoin Morgan flailed at a slower ball and was well-caught by wicketkeeper Haddin.

Morgan's sixth-ball duck was his fourth in five innings, including the last warm-up against Pakistan, and left England reeling at 5 for 73.

Marsh, who had earlier dismissed opener Ian Bell (36), Joe Root (5) and Gary Balance (10), then completed his five-wicket haul when Steven Smith took an extraordinary catch at short cover to dismiss wicketkeeper Jos Buttler.

Diving high and to his left, Smith showed marvellous anticipation to snaffle a full-blooded slog, a high point in a sparkling effort in the field for the hosts.

Marsh was also the third bowler of the match to take wickets in consecutive balls, with Broad also missing a hat-trick after bowling opener David Warner for 22 and having Shane Watson caught behind for a golden duck.

James Taylor (98 not out) and Chris Woakes (37), who spilled a simple, head-high chance at midwicket to reprieve Finch in the first over, dug in for a 92-run partnership to flatter England's scoreline.

The match ended in an odd manner, with Taylor initially given out LBW. He successfully had the decision overturned on review but was denied the chance of a century after a second review showed Maxwell had thrown down the stumps with James Anderson short of his ground.

For Australia, the only blot in a dominant display was Watson's failure to score or take a wicket and a dropped catch by Finch when Taylor was on 20.

Long a contentious selection, the bulky all-rounder's place in the side is certain to come under heavy scrutiny as regular captain Michael Clarke prepares to return for the second match against Bangladesh on the comeback from hamstring surgery.
